Photodiode (Infrared sensor of NDIR CO2 sensor) Since the photodiode is a photo type detector, its response speed is overwhelmingly faster (typ. 2μs) than that of a thermal type detector. Therefore, by incorporating this photodiode into a NDIR gas sensor and combining with LED of an infrared light emitter, the power consumption can be reduced to the minimum. In fact, gas sensors that can be ...
